“…41,42 Abrasion resistance of rubber composites is a measure of their capability to offer resistance to fracture or tearing. 43 Abrasion loss can be expressed as volume loss and relative volume loss (RVL) with respect to standard rubber. The abrasion resistance of the zirconia-filled composites is determined by using an abrasion drum.…”

In Situ Zirconia: A Superior Reinforcing Filler for High-Performance Nitrile Rubber Composites

et al. 2020

Zirconia particles are generated into a nitrile rubber (NBR) matrix via a solution sol–gel method in a controlled manner. Formation of zirconia particles from their precursor (zirconium(IV) propoxide) occurs under optimized reaction conditions. As a result, the nanoparticles are embedded and well dispersed in the NBR matrix that results in a remarkable improvement in mechanical and thermal properties of the composite. Such reinforcement is not realized when the composites are prepared following the conventional technique of filler loading by physical mixing, although the filler content remains the same. Use of a surface active coupling agent TESPT (bis-(3-triethoxysilylpropyl) tetrasulfide) in the reactive sol–gel system is found to further boost the mechanical performance of the composites. In order to ensure the practical application of the developed composites, a series of studies have been performed that consist of dynamic performance, swelling, thermal degradation, and resistance to oil, ozone, and abrasion. Analysis of the results reveals that in situ zirconia could be an excellent filler for the NBR composites to withstand in a harsh and adverse environment.

“…The problem facing the manufacture of thermoplastic glass powder composites is their poor compatibility with the thermoplastic polymer, and the only way to improve the compatibility between the two phases is to select a coupling agent that reacts with both glass powder and the polymer matrix. The most broadly used coupling agent “compatibilizers” are maleated polyolefins [ 12 , 13 , 14 ]. They are typically made by grafting maleic anhydride onto the polyolefin backbone via chemical interactions [ 14 , 15 ].…”

They are typically made by grafting maleic anhydride onto the polyolefin backbone via chemical interactions [ 14 , 15 ]. These linked malleated polyolefins can form many chemical bonds at the preparation temperature with hydroxyl groups on the glass particle surface [ 12 ], thereby strongly coupling the glass particles to the polymeric matrix [ 16 ].…”

Several reinforcement materials are incorporated into a polymeric matrix to improve the mechanical properties and reduce the cost of the obtained composites. In this work, recycled high-density polyethylene/waste glass powder composites, compatibilized with maleic anhydride-grafted polyethylene, were prepared using a two-roll mill and compression molding techniques. Four levels of waste glass powder, 2, 10, 20 and 30% by weight, and five levels of the compatibilizer, polyethylene grafted with maleic anhydride (0.5, 1.5, 2.5, 5 and 7.5%by weight), were used. The effect of adding waste glass powder and compatibilizer concentration on the composite's mechanical properties, such as tensile strength, tensile strain, tensile modulus and thermal properties was studied. The results showed that superior mechanical properties were obtained and that the tensile strength and modulus increased with increasing waste glass powder content and compatibilizer concentration by 20 and 1.5 wt%, respectively. However, the elongation at the break decreased with the increase in both factors. The composite, which was prepared under ideal conditions, has high thermal stability and can be easily recycled and reprocessed for five cycles with high mechanical properties. This study recommends that the prepared composite, under optimum conditions, can be used as a cost-effective automobile dashboard material.

“…In this section the presentation will focus on the production processes and properties of polymers made from chemically treated hemp feed stocks as opposed to those from untreated hemp fibers. Readers who are interested in studies that focus primarily on the physical and thermal properties of materials made from untreated hemp fibers can refer to studies by Wood et al, 112 Di Landro and Janszen, 113 Erchiqui et al, 31 Galzerano et al, 30 Li et al, 114 Le Trodec et al, 115 Sawpan et al, 116 Kabir et al, 117 Liu et al, 118 Liu et al, 119 Buitrago-Suescuń and Monroy, 29 Padovani et al, 8 and Sunny et al 120 Overall, there have been two strategies adopted for producing polymers from hemp; the first strategy involves the epoxidation and subsequent curing of hempseed oil, whereas the second strategy involves hydrolysis, fermentation, and separation of polymers that are naturally present in hemp. S ̌tevulováet al 121 used treated hemp shives to prepare lightweight composites.…”

“…To date, scientists and engineers have found numerous applications for hemp stems and hemp seeds, including in pulp and paper making, ,, building materials, − textiles, − porous carbon, − composite polymers, − biofuels, − essential oils, and chemical precursors. − Given the number of products that can be produced from cannabis, plus the expected worldwide growth in the legal supply of legal cannabis, it is becoming increasingly possible to envision cannabis as a feedstock in a circular economy, whose key characteristics include the increased use of renewable resources and the valorization of process waste streams. However, the current knowledge base of cannabis-derived bioproducts is spread out over a wide range of academic disciplines that spans science, engineering, agriculture, forestry, medicine, and public policy.…”

As societies place greater emphasis on sustainability, there is a move toward creating a circular economy in which renewable resources, such as agriculture and forestry residues, serve as feedstocks in the production of energy and chemicals. One emerging agricultural commodity that may potentially serve as a feedstock for numerous chemicals and materials is cannabis. For most of the last one hundred years the use of cannabis as a biomass feedstock has been all but impossible, due to its legal status. However, over the last 20 years the changing legal status of cannabis has resulted in a large number of studies which have investigated cannabis as a feedstock for diverse bioproducts, including polymers, pulp, and biofuels. Being a relatively new agricultural commodity, the literature on chemicals, fuels, and materials derived from cannabis is spread across numerous disparate disciplines, such as engineering, agriculture, chemistry, and biology. Thus, the purpose of this review is to compile and summarize the relevant studies that illustrate the use of cannabis as a feedstock in the production of chemicals, fuels, and materials as well as to highlight the challenges and possibilities for future research opportunities.
